Description
Technical field
This utility model relates to field of fluid control, is specifically related to a kind of gate valve.
Background technology
Along with the development of World Economics and improving constantly environmental protection requirement, world's industrial structure is also constantly being adjusted
Whole, therefore the use to ball valve is more and more extensive, and especially the protection to environment is particularly important and is widely recognized as.At present at oil
In the projects such as work, Coal Chemical Industry, Gas Industry, often leak at the sealing at filler.
Typically filler is set between valve body and valve rod, filler arranges gland, passes through between gland and valve body
Screw is fixing to be connected.If desired for when its sealing condition is overhauled, need, screw dismounting one by one, just to pull down filler pressure
Lid, it is dismantled trouble, brings inconvenience to maintenance.
Utility model content
It is readily accessible that the purpose of this utility model is to provide a kind of gland, the gate valve of good seal.
To achieve these goals, the technical solution adopted in the utility model is: a kind of gate valve, including valve body and valve rod,
Filler is set between described valve body and valve rod, filler arranges gland, between described gland and filler, filler is set
Gland, it is characterised in that: arranging a rotating connecting rod on described valve body, described connecting rod one end is hinged with valve body, another
End is provided with screw thread, and the edge of described gland arranges a U-shaped groove, and the end of thread of connecting rod can proceed in U-shaped groove and lead to
Crossing nut makes gland be pressed on filler pressing sleeve.
This utility model is further arranged to, and described gland is annular, and its lower end is against on filler, and upper end is provided with
The flange turned up, described gland is made up of elastomeric material, is provided with the metallic elastic bone corresponding with its shape in gland
Frame, described metallic elastic skeleton includes the metal flange turned up in ring skeleton main body and framework main upper end, described framework main
It is designed to corrugated tube shape.
This utility model is further arranged to, and the face of offseting of described gland and filler pressing sleeve is adaptive taper
Face.
The beneficial effects of the utility model: gate valve provided by the utility model, when removing gland, it is only necessary to pine
Dynamic nut, is producing connecting rod, so that it may remove gland easily from the U-shaped groove of gland to valve body with
The maintenance sealed between valve rod is more convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model gland.
Label implication in figure: 1-valve body；2-valve rod；3-filler；4-gland；5-filler pressing sleeve；6-connecting rod；7-U

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is described in further detail.Below
Embodiment is used for illustrating this utility model, but is not limited to scope of the present utility model.
Below with reference to Fig. 1 to Fig. 2, this utility model is illustrated.
A kind of gate valve, including valve body 1 and valve rod 2, arranges filler 3 between described valve body 1 and valve rod 2, filler 3 is arranged and fills out
Material gland 4, arranges filler pressing sleeve 5, described valve body 1 arranges a rotating connecting rod between described gland 4 and filler 3
6, described connecting rod 6 one end is hinged with valve body 1, and the other end is provided with screw thread, and the edge of described gland 4 arranges a U-shaped groove
7, the end of thread of connecting rod 6 can proceed to make gland 4 be pressed on filler pressing sleeve 5 in U-shaped groove 7 and by nut 8.
When removing gland 4, it is only necessary to loosen nut 8, producing connecting rod from the U-shaped groove 7 of gland 4
6, so that it may remove gland 4 easily so that the maintenance to sealing between valve body 1 and valve rod 2 is more convenient.
Gland 4 is annular, and its lower end is against on filler 3, and upper end is provided with the flange 41 turned up.
Gland 4 is made up of elastomeric material, is provided with the metallic elastic skeleton 10 corresponding with its shape in gland 4,
Described metallic elastic skeleton 10 includes the metal flange 102 turned up in ring skeleton main body 101 and framework main 101 upper end, described
Framework main 101 is designed to corrugated tube shape, use the gland 4 of said structure when the top by screw 5 is pressed, corrugated tube shape
Framework main 101 can along its axial direction generation elastic deformation, so coordinate compression spring provide double elastic seal, filler
Under the effect of double elastic power, elastic compression is on filler 3, even if so screw 5 occurs to loosen, at the work of elastic force for gland 4
Still filler 3 can be compressed, it is ensured that good sealing with lower gland 4.
The gland 4 that elastomeric material is made is when being squeezed, and self also can occur elastic deformation, at valve rod and valve body
Between also can play the effect of elastic packing.
The face of offseting of gland 4 and filler 3 gland is adaptive taper surface, and this is configured such that gland 4 can be more steady
Fixed, uniformly, accurately top be pressed on filler 3.
The above is only preferred implementation of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of without departing from this utility model know-why, it is also possible to make some improvement and modification, above-mentioned vacation
If these improve and modification also should be regarded as protection domain of the present utility model.
